Didn't know about that. Interesting, that by default, /usr/lib/portage/bin/ is not in the PATH. I wonder why.

That file does not exist on my compy... running portage 2.1

Well, the post you quoted is over 3½ years old. IIRC, it was gone also in the later 2.0.x versions._________________Please read our FAQ Forum, it answers many of your questions.

If you keep your database updated (daily cronjob of update-eix), that will list everything REAL fast.

Also, you could also cat the file, and if you want,

eix -vI >> installed_apps

to give you a good listing of all your installed files with nice little descriptions of which you can then cat && grep through for a refrence from then on.

Enjoy.

P.S. You could run update_eix && eix -vI >> /path/to/file to keep an updated list handy. Personally, I drop those files in my /home/user dir, and then I can just cat from there.
